Abstract
Provided are method of controlling nozzles of an inkjet head and an apparatus for measuring the amounts of ink ejected from the nozzles of the inkjet head. The method includes: preparing a mass measuring device, which measures the mass of ink by using an oscillation change, in a pixel; ejecting ink into the pixel from a nozzle of the inkjet head, and measuring the amount of ink ejected from the nozzle by using the mass measuring device; and adjusting a voltage waveform applied to the nozzle of the inkjet head.
